After lots of research, I finally decided on laying porcelain slabs in my back garden - a contemporary look and low in maintenance. I ordered them myself, they arrived - 20mm thick and looked lovely. I had a patio laying company lined up, but it was clear they didn't know what they were doing. I changed the team and sent across loads of videos plus advice from this website on how best to lay them. It's not a great job, spacing is irregular but I'm kind of committed. They finally did the jointing today which was a grey powder resin that was brushed in. While the slabs are a pale grey, there's a darker grey patchiness all along either side of the joints. Is this normal and will it go once the slabs are all washed down?

That staining is known as 'picture framing' and it really shouldn't happen with good quality porcelain.
Was the surface thoroughly wetted before they brushed in the jointing? When resin-based jointing is used without pre-wetting, it can cause severe picture framing but this is unusual with porcleain, as I said, so it would be useful to....
a) see photies of the damage, and
b) know just what was used for the jointing - brand name and product name....and
c) the supplier/brand name for the porcelain
